[0003] The structure of the hollow blade dryer can refer to the authorization announcement number "CN 219037456 The utility model discloses a "anti-sticking hollow paddle dryer". A cleaning piece is arranged on a connecting shaft. The rotation of the connecting shaft drives the cleaning piece to rotate, so that the cleaning piece scrapes off the material attached to the paddle, thereby reducing the difficulty of the material to adhere to the paddle during the stirring process, thereby making the material in the chassis less likely to be silted and blocked, thereby improving the efficiency of drying the material in the chassis. At the same time, the paddle is spirally arranged on the hollow rotating shaft, and the paddle is hollow and connected to the hollow rotating shaft. A heat transfer medium is connected to the hollow rotating shaft, thereby increasing the contact area of the heat exchange surface formed by the hollow rotating shaft and the paddle during the stirring process of the material in the chassis, thereby improving the drying efficiency of the material, and solving the problem that when the existing hollow paddle dryer is drying some materials with high viscosity, the material will adhere to the paddle, which will reduce the fluidity of the material in the chassis after a long time, and the material in the chassis will be blocked, which will reduce the drying efficiency of the material and require manual cleaning of the paddle after shutdown.
